" matic Lamp-Extinguisher,,of which the following is afull, clear, andexact description: Our invention relates; to automatic lamp extinguishers, our more part'cular purpose 'tion of the arrow, through a lam being to provide an a rove construction contaimng a,w1ck snu er co-act ng in con.-

.nection with a weight, to extinguish the flame whenever the lamp is thrown over upon its 'side or is inclined beyond certain limits in any direction.

More particularly stated, our invention comprises mechanism for rendering the extinction of the flame as nearly positive as practicable, in order to reduce the possibility of a conflagration in case of the accidental overturning of the lamp.

Reference is to be had to the accompanying drawings fo a partof thiSspecification, in which si ar characters of refer-' 'ence indicate-corresponding parts in'all the figures Fi ure 1 is a centralvertical section on the hne 1--'1 of Fig. 2, looking in the direcburner provided with our improvement, t is view showing a spherical wei ht resting in a receptacle having a conica bottom so as to keep the weight normally centered, and a disk resting on the weight and connected by afork with a pair of snuffers and ada ted to actuate the same for the purpose 0 extinggisbing the flame whenever the weight placed beyond a certain limit; Fig.2 is a honzontal section upon the line 2'2 of Fig." 1, looking in the direction of the arrow,

and showing the wick, the burner tube, the snufiers and the fork for actuating the snufl'ers; Fig. '3 is an enlarged fragmentary side elevation showing the manner in whic the snufiers are pivotally mounted upon the .ulplper end of the burner tube; Fig. 4 is an rged fragmenta section showing the snufl'ers as c osed a ove the wick for the urpose of extinguishing the flame of the lhtter; and Fig. 5 is a view partly in section and partlyin elevation, showing the snulfers as closed as in Fig. 4, the view being otherwise similar to Fig. 3.

At 6 ig shownaburnercasing which is provided with air holes 7. A burner tube appears at 8, and extending partially into it .is a star wheel 9 mounted upon a revoluble stub shaft 10 in order to enable it to be turned-by hand. The star wheel 9 e s I the wick- 1-1 and is adapted to raise and ower the same relatively to the burner tube in the manner heretofore understood in this art.

. At '12 is a burner screen consisting of a perforated plate disposed horizontally and reaching entirely across the burner casing.

, .A pair of snutlers 13, 14, each having substantially the form of a sector-shaped hood, are pivotally mounted upon pins 15, the

lattter beingsecured rigidly upon opposite sides of the burner tube 8. The sectors 13,

14 are provided with slots 16 into which extend tines 17 of a fork 18. The arrangement is such (see Fig. 3) that when the fork 18 is raised or lowered, the hoods 13, 14 are rocked upon the pins 15. The hoods 13, 14 are provided with bearings 13, 14 integral with them. The hood 13 is further provided with a bead 13 (see Fig. 4) adapted to slightly overlap the adjacent edge of the hood 14.-

The burner casing 6 is provided with a cap 19 having an a erture 19 from which the flame issues w ile the lomp is burning. Mounted partially within the burner casing 6 and secured rigidly u on the burner tube 8 t is a cup 20 provided with a conical bottom 21 A1 spherica weight 22 is free to move in the cup 20. Mounted rigidly upon the fork 18 is a disk 23 of slightly smaller diameter than the cup 20. This disk normally rests upon the welght' and is adapted to slide vertically in relation to the cup. When the weight 22 moves .in a direction lateral to the eneral verticalaxis of the cup 20, the dis 23 is moved upward by the displacement of the y .This is because of the inclination of the bottom 21, owing to its conical form. ,The cu 20 is provided with a cover 24, through w ich.the fork 18 extends, this fork being gluided by the disk 23, the cover 24 and the urner screen 12, through which cupies its lowermost position on the conical bottom 21. If, however, the lamp be accidently thrown down or turned in sucha direction that the burner tube 8 is inclined beyond a certain limit, the Weight 22 being displaced from its normal position and tend-- 'ing to follow the inclination of the conical bottom 21, moves slightly in a lateral direction relatively to. the burner. tube 8, the resultbein that the fork 18 is pushed slightly toward he upper end of-the burner tube,

This movement causes the hoods to rock upon the pivots and to. assume the posi- 10: tion'indicatedfin FlgSg4 and 5,- thereby extinguishing any flame there may beissuing from the upper end of the wick 1 1.

It will be noted that whenever the lamp is lighted,- that is to say,'moved into its normal lowposition' as indicated in Fig. 1, the weight 22 rolls into the middle of the conical bottom 21,

thus restoring ail parts controllable the Weight to their respective normal positions. I having thus described our inventil-in, we

claim as newand desire to secure by Letters Patent:

The combination a burner, of a pair of snufl'ers movable toward and'from each other, 'forthe purpose of extinguishing a flame associated with said burner, a cup p'r0 vided' with a conical bottom in connection ,with the-burner, a weight disposed within the cup and resting upon the bottom} a disk above the Weight and movable in the cup, and a connection between the disk and the snufi'ers for actuating the same when the weight is moved.

In testimony whereof We have signed our i names to this specification in the presence of 'lnuQTHYMCGRATH, v MARTIN'M. HAZLETT.
